therefore, the sum of this infinite geometric series can be calculated using the formula .
So,
If 2 is the sum of this infinite series, then you'll never reach it.
14.17 because the 4 takes the place of the units column and the 7 takes the place of the thousandths column in decimal places. The first column after the decimal point is the tenths column.
$520 was earned by carl in last week
Step-by-step explanation:
(1/2 X - 20 ) = 240
1/2 X = 240 +20 = 260
X = 260÷1/2 = 520
verification
520 ÷2 = 260 - 20 = 240
Hence proved
Answer:
6 apples, 21 apples, 30 apples respectively
Step-by-step explanation:
Let us first start by writing <u>expressions</u> so that we can easily solve for the problems below.
Let us suppose Alice is x. In this case, Claire has 3 times Alice's apples, so 3x.
1. If Alice has 2 apples (x), then Claire has 3x
3*2=<u>6 apples</u>
Claire has 6 apples.
2. If Alice has 7 apples (x), then Claire has 3x
3*7=<u>21 apples</u>
Claire has 21 apples.
<u />
3. If Alice has 10 apples (x), then Claire has 3x
3*10=<u>30 apples</u>
Claire has 30 apples.

<span>Simplifying
3z + 9 = 0
Reorder the terms:
9 + 3z = 0
Solving
9 + 3z = 0
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + 3z = 0 + -9
Combine like terms: 9 + -9 = 0
0 + 3z = 0 + -9
3z = 0 + -9
Combine like terms: 0 + -9 = -9
3z = -9
Divide each side by '3'.
z = -3
Simplifying
z = -3
